More than twelve months ago, Mercedes-Benz and Renault-Nissan agreed on a joint program to develop the next-generation Smart. But despite several attempts, a more widespread, all-encompassing global cooperation agreement has yet to be signed. The deal, which would change the face of this industry, likely includes a swap of shares, a near-total component integration of all five brands involved, and a close cooperation in numerous vehicle segments including vans and light trucks. Rumors suggest that Renault/Nissan's Carlos Ghosn and Mercedes' Dieter Zetsche may announce further details in May.
